344 SUMMARY OF CURRENT RESEARCHES RELATING TO 



occur in Japan which, though referable to well-known genera, present 

 peculiarities so anomalous as to necessitate a revision or amplification of 

 the original generic characters. 



Muscinese of China and Indo-China.* — E. 6. Paris publishes his 

 seventh article on the Muscineae of Eastern Asia, comprising fifteen 

 mosses gathered by the missionaries Courtois and Henry in China, in 

 the provinces of Ngan-Hoei and Kiang-Sou ; twenty-four collected by 

 Eberhardt in a very humid climate in the south-east of Tonkin ; and 

 twenty-five collected by the scientific exploring mission of Indo-China 

 in Laos upon the Than-Hoa-Luang-Prabang road, which follows the 

 parallel 19° 40' lat. N. In all thirty-one species new to science are de- 

 scribed, and appended are descriptions of two new species of Calymperes 

 obtained from Panama and New Caledonia. Finally, F. Stephani sup- 

 plies a list of five species of Hepatic* from Laos. 



Indian Bryophyta. — E. Levierf publishes some corrections of mosses 

 issued in his " Bryotheca Exotica," Series I. (l'J07). J. F. Duthie $ has 

 revised and supplemented Sir Richard Strachey's "Catalogue of the 

 Plants of Kumaon." On pp. 234-242 is an enumeration of 102 mosses 

 and 18 hepatics collected by Strachey and Winterbottom in 1846-9 

 in Kumaon and neighbouring districts, and determined by Mitten. 

 E. Levier,§ commenting upon Strachey's Catalogue, adds a personal 

 note upon the great services rendered to bryology by J. F. Duthie 

 when superintendent of the Saharnnpur Gardens, and by his successor, 

 W. Gollan, now deceased. These two, by their own efforts and by the 

 employment of English and Indian collectors, amassed considerable 

 quantities of Bryophyta from the North-West Provinces, Tibet, the 

 Eastern Himalayas, the Central Provinces, and even from Upper Burma. 

 Kabir Khan, in particular, has shown himself to be a specially successful 

 and energetic collector, having found several new species, and having 

 ascended to an altitude of 19,000 ft. to obtain some rarities. 



Sapehin, A. A. — TJeber das Leuchten der Prothallien von Pteris serrulata. (Con- 

 cerning the luminosity of the prothallium of Pteris ser- 

 rulata.) 



[The cause of this phenomenon is the same as in the 

 moss Schistostega osmundacea, viz. refraction of 

 light by the cells.]

„ „ Die Ursachen der Wasserfiillung der Sacke von Lebermoosen. 



(The causes which bring about the filling of the sacs of 

 hepaticse with water.) 



[The author raises objections to the experiments of 

 Goebel, and demonstrates that hepaticse when 

 moistened suck water into their sacs in con- 

 sequence of the increase in their volume.]
